I had the same problem and the only way I could trun the TV off was to unplug it. I took it to a shop and they said it needed a Main board/ A board. They seemed to think that it was a victim of a power surge. The part is around $170 used and $500 new. It is a very rare board so i am still looking for a used one. The part number is TNPH0716ABS.

Hi,
TV needs lamp replacement as existing lamp got weak or has been reached to end of its working life, please note that lamp is not dead or broken so that is why lamp lit is not lit at tv front.
Hope these info will help you.
